ABSTRACT:
The rolling mill stand, for example a four-high rolling mill stand, for strip mills, with adjusting devices acting horizontally and/or vertically on the rolls for roll nip regulation is characterized by a dual bearing for the work rolls (1, 2) in respectively two inner and outer mounting members (5, 6), which latter, for attaining the same change in shape over the strip width, are horizontally adjustable by deflecting the rolls (1, 2) in the horizontal direction by adjusting devices (7, 8), as well as by a positional control of the inner and/or outer mounting members (5, 6). With the aid of the horizontal deflection device, a position-controlled horizontal adjustment of the work rolls (1, 2) can be performed for compensating for the horizontal forces and/or for a strip thickness regulation while maintaining the horizontal bending curve (13) of the work rolls required for planeness of the strip (14).
